Floating ammeter design provides stable measurements for both loating and grounded DUTs (continued) Grounded DUT coniguration Figure 2 shows the case where one of the ends of the DUT is grounded. In this case the con- nection scheme shown in Figure 1 cannot be used.

- Page 7 View function key. Note: In case of the B2981A/83A the instrument boots-up into this state and these operations are not necessary. Step 2. Check if the Voltage Source ield is set to 0 V. If not then follow the steps shown below to set the output voltage to zero volts.
- Page 8 Step 6. (1) Continue rotating the [Knob] and increasing the voltage until the current is between 10 to 20 mA. Note: If using the B2981A/83A then increase the external voltage source voltage. (2) The LED starts to emit light at around 1.5 V.
- Page 9 This example outlines how to plot LED current versus voltage (I/V) characteristics and it only applies to the B2985A/87A. Note: If using the B2981A/83A then you need to plot the current measured by the B2981A/83A and the voltage applied by the external voltage source on a PC to make this same type of I/V plot.

(1) The Source function graphic changes to linear single sweep (upper right corner of screen). (2) Edit the sweep parameters as shown in the igure to the following values: - Start: 0 V - Stop: 1.8 V (or the anode voltage that lows about 10 ~ 20 mA anode current.)

Press the [Single] key. The Trigger indicator changes to [ARM], and the sweep measurement begins. By pressing the [Auto Scale] function key, intermediate measurement data can be seen on the 10 X-Y graph.
